Formula Used in Window Cost Calculation
The calculator uses a simple but powerful formula to compute total project cost.
1. Subtotal Formula
Subtotal = (Number of Windows × (Cost per Window + Labor Cost per Window)) + Installation Fee
2. Tax Formula
Tax = (Subtotal × Tax Rate) ÷ 100
3. Final Total Formula
Total Cost = Subtotal + Tax
Example Calculation
Let’s understand with a real-world example:
- Number of Windows = 10
- Cost per Window = $150
- Labor Cost per Window = $50
- Installation Fee = $200
- Tax Rate = 8%
Step 1: Subtotal
Subtotal = 10 × (150 + 50) + 200
Subtotal = 10 × 200 + 200
Subtotal = 2000 + 200 = $2200
Step 2: Tax
Tax = 2200 × 8%
Tax = 176
Step 3: Total Cost
Total = 2200 + 176 = $2376
